There is not enough information to diagnose the problem. The more information you give us, the better we can help.
What does the rest of the plant look like? How old is the plant? When did it start? Indoor or outdoor? What soil/medium are they in? Temperatures? Humidity? You feeding nutrients? What brand? EC, pH? How often and how much do you water?

Every bit of this…
Looking at a single leaf with no info doesn’t help you find out what’s wrong nor us to be able to help … can say it looks like this or that, but can’t be positive.
As far as spraying for bugs, a good ipm is the way to go, but if you had a good infestation don’t be expecting that it got sprayed twice so it’ll be completely ok… More have to worry about eggs in your soil and on your plant, since they’ll hatch for weeks depending on the infestation

There are different reasons that that happens

Outdoor
Plant is in preflower stage
Soil ph 6
I use not branded fertilizers
Watering is ok
Temp a litle high 32/33 the highest in day
I have used clasic nitrate & phosphorus both a little (not used potasium)
Plant is topped and trained… so in my opinion might be potasium deficiency/ heat stress / stres from training or magnesium deficiency
(Today burned tips are going upward)
My englisht is bad so sorry if i have made a mistake.

If it is just the lower leaves that is normal and I wouldn’t worry too much. Focus on the newest leaves and buds.
Maybe a little bit of heat stress, but 33°C isn’t too bad.

I personally dont think the issue looks that bad. I agree with slight heat stress but it doesn’t look like something to worry about less so as it’s localised to the lower portion of the plant. I think if he watered more often the issue would go away. 
@Miku it’s a plant. Water and let it grow buddy
Edit - heat stress when you should worry. Only reason I’ve not stripped the leafs is they are over ripe and I’ve not got time to Chop them till Sunday

I’d suggest repotting the plant careful not to compact the roots (don’t cringe, root trimming 
)…might want to try dwc. I bet you have a heavy perlite mix and you are moving the pot around alot.
yes i am moving it a lot with sunlight and there is perilit it is bad ?
